, This invention relates to machines 'for effecting relative movements between shoes and their lasts, and is herein illustrated as embodied in a machine in which such movement is eflectedby a roll acting against the counter portion of a shoe' to pull the shoe from the last. For an example ofk a last pulling machine of' this general type reference may be had to the copending application of- `Arthur lPym, Serial 2N o. 58,163, filed April 2, 1921'. It is to be understood, however, that in various novel and useful aspectsthe present invention is not limited. to machines of the type shown in that application. n l i The `machine disclosed inthe above-mentioned applicationV to PymjV includes in its lorganiZa-tion a support for a last with a shoe thereon, aroll, and means'for moving the roll bodily to bring it into engagement with kthe counter portion of the shoe, One' of the objects Oi thepresent invention is to provide a machine 'of more simple construction wherein the driving mechanism whichy rotates the roll isnot required to accommodate any bodily kmovements of the roll. In accordance' kwith thisfobjecuone feature of the present invention `consists in the provision ot' means for moving the last support to bri-ng the counter portion ofthe shoe into engagement with the roll.

Anotherobject yof the invention isto prevent such undue Wear Ot'l the roll, ror other member having-a" shoe-engaging surface, as `might Occur 11v the engagements 'between the shoes and the member always take placeat the same portion of the shoe-engaging surfacethere'o'f. yW'ith a View to preventing suchlocalied Wear,v another feature of the invention yconsists in the provision ot means for causing engagements between. successive shoes and different-"portions of the-.shoeengaging surface, respectively. InI the illustrated machine the meansl 'or causing engagement with successive shoes tor take place at different portionsl of the shoe-engaging surface is actuated automatically bythe mea-ns for causing relative movement of approach and of separation between the last support and the shoe-engaging member or roll, andthe direction of the relative movement which causes successive shoes tov engage diiierent portions of the shoe-engaging surface is transversely of the shoe and axially O1' lengthwise of the roll.

In casesI Where the machine is to be employed as a last pulling machine, it is desirable tO make some provision for holding the last uponl the last pin against the action of the member which engages and moves the shoe. Accordingly, another feature of the invention consists in the provision of means which not only acts upon4 the last pin to urge the' shoe Aagainst the surface of the member, but which also at the same time tends to urge the last on the last pin. Where the member which acts upon the shoe is a roll, this result is accomplished by providing such any inclination between the direction of the lastpin and the line of thrust between the last and the roll as to tend to hold the last from slipping from the last pin. Provision is also made for adjusting the position of the last pin support toward and from the roll Without varying this inclinationof the last pin.

The above and other features of the invention, including details of construction and the arrangement of the actuating mechanism, will now be more particularly described With reference to the accompanying drawings, in Which f Fig. 1 is a side elevation of a last pulling machine embodying the invention in a preferred form;

In the illustrated machine for separating shoes and lasts, the machine comprises a hol- ,low frame l() which enqloses mechanism tending into af slot 88 v formed in the rod Provisionis made for swinging the lever i70?'inwardlv `toward the roll 12. To this extension 'oftlie'arm 90 is carried uponl the' inner end of the arm" 90. Ther arm 9 0' is so designed and tl1efstud92 is so secured to the. arm S10-to make the stud 92 coaxialy ith the vsleevek when the lever 7051s in po. LAon iorv the shoe to engage the central j portion of the roll-12.4 forwardly extending treadle :94'is ulcrumed upon a shaft 86 carried' at the rear portion of: the baseoffthe traine 10. A oeil sprhig 98 having one end'secured to a forward por ion ot the treadle 94 `and the other end secured to an eye which'is fixed on the vframe,tends to hold the treadle 94 in its uppermost position. .11' rod 100 ispivotally secured at 'its lower lend to a forward portion of the treadle 94 and at'its upper end to 'a lever 102 which is zt'ulcrumed atf`104 to `the upper portion ot the rear wail oiI the frame 10 and extend" forwardly. A link 106 has a forked enel which is trunnioned to a sleeve rotatably Acarried `upon the stud 92, the other end ofthe link 106 being likewise forked andy bic-inlnf similarly connected, by meansv of a stud,` a sleeve and atrunnion, to the lever 102. The link 106`is thus yuniversally pivted atk its ends thev lever and the lever 102, respectively. kIt is 'apparent that d-eiression of -the 94 against rthe 'if sion of the spring 98 will pull down the rod-100, rotating the lever 102 in a counterclockwise direction as viewed in Fig. 4, thereby depressing the rod 106 and swinging the lever '70ina clockwise direction. lhe rod is inadeadjustable lengthwise by forming it in two partsy which slide lengthwise of each other and which may be clampedv in ygiven .position by means ot aeianiping'block 108. f Y

Y Provision is madek tor automatically shitting the position of the' lever 70 longitudinally of they roll 12 ior each inward movement ofthe lever 70 to preventthe wearing ci: a groovein the central portion of the roll 12 and to distribute the weary over the entire roll. To this end, a slot 110 (Figflyexf ending' lengthwise of the ylever 70 is formed in the intermediate portion of the lever 70. Anopening 112 isftormed in the front wall of the frame 10 adjacent to the slot 110 and a bracket 114 forming a cover plate for the-opening 112is bolted to the front wall o'flthemtrame'lO at this point. The bracket 1141's formed yto provide ahearing for a stub shaft 116 which extends horizontally through the r bracket 114 from the vinterior space ena closed byl the trame r10 togthe outside of the bracket 114. yA short crank 118 (Figs and 6) is mounted upon the outer end ot'y theshaft 116 and carriesk an eccentric pin 120 which extends loosely into the slot 110.` The crank 118 is secured to the shaft 116 and eccentric pin 120 by means of bill bind-v ders 122 of the type previously described. The inner end of the shaft 116 carriesy a worm wheel 124. For driving the worm wheel v124 a worm 126 is carried on a shaft 128 journaled' in aninwardly extending portion of the bracket 114.

rotated by the downward movement of the rod'100. Toy this end a pawl lever 132 isloosely mounted upon the hub of the Worm 126 and carries a pivotally mounted pawl 134. A second pawl 136 also engages thev ratchet wheel and is pivotally mounted at 137 upon an extension of the bracket 114. The two pawls 134 and 136 areheld toward each4 otherY and iny engagement with 'the ratchet wheel '130 by means of a tension spring 138. The pawl lever 132 is urged in a counterclockwise direction, as viewed in F ig. 6, by a tension spring 140 one end of which is secured to the pawllever and kthe otherend of which is secured to a pin 142 which extends horizontally fromfan eXtension of the bracket 114. The pin 142 serves also as a stop for the pawl lever 132 against the action of the spring 140. A block 144, which is slidably clamped for purposes of adjustment about the rod 100, engages the pawl lever 132 but clears the end of the pin 142 so that upward movement of the rod A ratchet wheel 130 fixed upon the hub of the worm 126 is 1.00 willrotate the pawl lever 132 and theres lever 132 will be rotated in a counter-clockwise direction, as viewed in Fig. 6, by the spring 140 as far as permitted by the pin 142, while the pawl 134 will ride over the teeth of theratchet wheel 130 and the pa-Wi 136 will hold the ratchet wheel 130 from rotation. For each upward movement of the treadle 94 under the influence of the spring 98, the ratchet wheel 130 will therefore be urged through ,a definite dist-ance and, through the gears 126and 124, the shaft 116 andthe crank 118, the crank pin 120 will be rotated. Such rotation of the crank pin 120,`aoting upon the side of the wall 110, will cause a swinging movement of the lever' 70 longitudinally of the roll 112. vA, stop kin 146 limits upward movement of the block 144 andthus determines the outward position of the lever 7,0. Atstop member 148 in the form kof a sector pivoted to the forward lower portion of the frame 10 may be swung down to engage the treadle 94 vdirectly. In this case, the stop member 148 is employed independently and in place of the stop pin 146.

Mounted upon the upper portion of the frame and adjacent tothe roll 12 is` a support for a cutting tool comprising a xed knife150 (Fig.V 1) for cutting the laces of shoes and a guard 152 for protecting the shoes from the knife 150. Similarly mounted upon the upper portion of the frame 10 isv a. stationary pin 154 over which the operator may force the hole of the instep block of a block last to release the-z instep block. I v .s Y

. In'Fig. 7 is shown a shoe S in the process of removal from a last L. While the shoe S is illustrated in Figs.v 4 and 7 as having a heel H, thereby indicating that the shoe is substantially complete, itv is to be understood that the application of the-machine is-not limitcdvto the separation of completed shoes Afrom their lasts. On the contrary,

' j themachine serves equally well to separate shoes from their lastsat an early stage of their manufacture. It will be observed that the last pin 72, when holding the last L in position for the shoe S to engage the roll 12, is inclined toward the plane of taugency, indicated by theline T--T on Fig. 7, of the shoe S and the roll 12. That is, the free end of thev pin 72 is closer to this plane of tangency T-T than the end which is secured tothe lever 70. kThe purpose of this inclination is yto prevent the upward force of the rotating roll' upon the shoe from lift- I 9 ing the last from the pin 72. As the shoev is urged against the roll 12, the thrust of the roll 12 endwise of the shoe and of the last will be exerted in a direction normal c to the plane of tangency T-T and will tend to force the last downwardly von the pinr 72,

because of the inclination of the last pin 72 to the lineof thrust `referred to. As illustrated, the angle of inclination between the last pin 72 and the plane of tangency of the shoe and the roll is about 5 degrees, this particular magnitude having been determined by experiment as desirable.

Owing to the variation in the size of and y shape of shoes, the distance between the last pin hole and the rear end of the shoe will vary for different shoes. It is therefore desirable to provide an adjustment for the fulcruin of the lever 70 which will permit the leverY 70 to be moved toward or from the roll12 while maintaining the lever 70 parallel to its former position, that is, withvout varying the angularly Vposition of the lever 7 O about the trunnion pins 68, so that the last pin v72y will always incline toward the plane of tangency of the shoe and the roll Vat an angle of approximately 5 de- -v grees when the shoe is in engagement with the roll. To this end the sleeve lmay be adjusted, by loosening the bill binder. previously described, outwardly on the sleeve 58 to accommodate shoes wherein the distance between the last pin hole and the heel end of the Vshoe is relatively great, and likewise the sleeve 60 may be adjusted inwardly for shoes wherein this distance is relatively small. rlhis adjustment also `enables the operator to take up any wear in the roll by adjusting the sleeve 6() inwardly to accomin odate the reduced diameter of the roll;

It isV further desirable, for the reasons stated in the preceding paragraph, that the line of adjustment of the fulcrum of the lever 70, or in other words the common axes of the sleeves 60 and 58 and of the stud 56, be parallel to the direction of movement o the heel endof the shoe at the instant'of engagement of the shoel with the roll 12 as thelever is swung toward or from shoe engaging position. 1f the liner of ad-` justment Iwere otherwise than parallel Vto this direction of movement of the shoe, the point of tangency of the shoe and the roll would vary, and the angular relation between the last pin 72 and the plane of tangency T T would also vary. It is apparent that if, when a shoe is in engagement with the roll 12, the axis of the trunnions 68 be positioned ina planenormal to the axis of the sleeve 60 and passing through the point of contact between the shoe and the roll, then the swinging movement ofthe end of the shoe toward and from the roll will necessarily be parallel to the axis of the sleeve 60. The lever 70 is therefore designed to satisfy this condition for shoes wherein the distance between the last pin hole and the end of the shoe is of average amount. In the case of a shoe wherein this distance is greater than the average, itis necessary, in order to maintain thefive degree inclination of that last pin, to adjust the sleeve- 60 outwardly, so that gthe trunnions 68 will be positioned outwardly of the desired point, and in the case of shoes wherein this distance is less than the average, the sleeve 60 mustbe adjusted inwardly and the trunnions 68 will be positioned inwardly of the desired point; but the effect of such departure of the position of the trunnions 68 upon the path of movement of the slice, and therefore upon the position of the point of tangency ofthe shoe with the roll, will be so exceedingly slight as to be negligible.

The thrust developed between the roll 12v ment; and since this direction of movement-v of the heel end of the shoe is, asstated in the preceding paragraph, parallel to the fso '72:5' determinedby the distance of the stud 56 i engage the roll 12 atfsuch a point as to y axis of thesleeve, the plane T-T should .the centralportionof the roll 12, that is,

, ywith the lever 70, as viewed in Fig. 2, in

upright position. Since the last pin 72 is inclined at an angle of about 5 degrees to a plane normal to the aXisof the sleeve 60, for

vthel'same position of the lever 70, it follows .thatthe angle. between the axes of the'last pin 72 and the'study 92,V respectively, is about y 85 degrees, this, angle. being the same Whatl Vever ymay be lthe angular position of the n lever 70, since the last pin 72 and the stud 92. are, in etlect,portions of the lever 70. The location `of the axis of the trunnions 68 will he determined by the intersect-ion of the axis of the stud 92 with a plane normal I to the axis of the stud 92y and tangent to the heel end ofv ank average shoe yon a last on the. pin T2.y The length of the lever 70. is

from the roll l2,y the lever 70 being of such lengthy that when a last L for a shoe S of average height and having a thimble hole of average depth is mounted on the last pin 70, the heel end ofy the. shoe. S on the lastfwill 'Y make the plane of tangency T-T between the shoeand the roll normal to ythe sleeve 60, v The previously described heightwise. adjustment of the last pin 72 by the lignurled head 82 enables the 'operator ,tof accommodate lasts for shoes of various heights and having thimbl'e holes of various y,gagin'g position, isl inclined toward the roll depths without varying the above-described ,pointofengagemenn and therefore without varying the plane of tangeney T--T.v l

ForI convenience, as. previouslystated,v the stud 5,6fis horizontal. The plane of tangency n ofthe shoe and the roll is, therefore vertical, andthe last pin, when the shoe is in roll enatan angle of about 5 degrees from the vert-ical; The link 10.61 is so arranged as to j. be vertical when the stud 92 is coaxial with v the sleeve 6.0,- and when the latter is adfjusted on. the sleevev 58 for an average shoe.

Adjustment ofy the sleeve in or'out for a shoefother ythan average may thusswing the link *10,6 about. its upperpivot without substantially varying the position "of the lever 102,01; of the, treadle 94. In other words, the lever ZO maybe adjusted toward or from kthe vroll l2v independently of the treadle 94, the 'rod 100, theleverr102 and the link 106. Adjustment, of the sleeve 60y in orl out on ,the sleeve 58 will alsovary the normal or clearance position of the. lever4 'ZO as determined by the bloekrllt for the stop 148 independently of ythe meansl forl swinging the lever 79 ytoward the roll 12, and without the axis of K tudinally ofy the roll will merely swingthe, its upper pivot without sub` link 106v about stantially affecting the lever 102 or the treadle mechanism.
